A running JellyTau currently reports no version anywhere: not in the UI, not in the logs. When a user reports "the equalizer does nothing on my device" there is no way to tell whether they are on the v0.2.0 tag, master, or a three-week-old local debug build — a live gap given v0.2.0's Android audio settings are not yet device-verified. Specifies a build.rs-emitted `git describe --tags --always --dirty`, a typed BuildKind (Release/Untagged/Development/Unknown) classified in Rust rather than pattern-matched in the UI, a get_build_info command, startup logging, and a Settings > About block with copy-to-clipboard for bug reports. Explicitly does NOT derive the release version from git: Cargo needs a literal semver at manifest-parse time, so sourcing it from a tag would trade a reviewable bump for a build-time dependency that fails in CI's shallow Docker clones. The release version stays authored; only the provenance is derived — they answer different questions. Two constraints found while writing this: - Only publish-docs.yml sets fetch-depth: 0. build-release.yml has five checkouts and build-and-test.yml two, all of which would stamp "unknown" as-is. Flagged as an acceptance criterion. - tauri.conf.json's version field can be dropped to fall back to Cargo (three hand-bumped files becomes two), but gen/android/app/build.gradle.kts reads versionName/versionCode from generated Tauri properties, so that must be verified before adopting rather than assumed.
